Analysis of the Bonding Behavior and Joining Mechanism during Friction Press Joining of Aluminum Alloys with Thermoplastics

Friction Press Joining (FPJ) is a joining process for the production of multi material combinations of aluminum alloys and (fibre- reinforced) thermoplastics in lap joint configuration. It is based on a modified Friction Stir Welding (FSW) process. This study investigated the influence of the main process parameters (axial force, rotational speed, feed rate) of FPJ on the bonding behavior and joining mechanisms of glass fiber reinforced polyamide 6 with the aluminum alloy EN AW-6082.
